IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 118,859, datedSeptember 12, 1871 antedated September 2, 1871.

To all 'whom it may concern:

Be it known that I, J ULiUs JoNsoN, of Baltimore, county of Baltimoreand State of Maryland, have invented a new and useful Improvement inDeep Well and Force-Pumps for lVater, Oil, Sac.; and I do hereby declarethat the following is a full, clear. and exact description of the construction and operation of the saine, reference being had to the annexeddrawing making a part of this specication, in which- Figure l is a plan3 Fig. 2, a sectional elevation; Fig. 3, an enlarged plan through c' Zof Fig. 2. Fig. 4 is an enlarged section of the strainer and barrel, andFig. 5 a section of the strainer.

My invention has for its object the construction of a cheap and simplepump for deep wells of water, oil, or other substances; one that can beput up by any person of ordinary capacity 5 neither contains partsliable to get out of order, nor likely to be seriously affected by anyforeign substance or impurities which might pass through the strainer.

It consists of a casting, g, Figs. 2 and 4, forming the pump-barrel andstrain er in the one piece, and having on its upper end a suitableiiange for connecting with the other part-s of the pump. Within thisbarrel is cast a brass sleeve or bushing, ZL, shown in detail on Fig. 4,bored out and having turned in it a couple of shallow grooves, Z i, Fig.4, commonly known as packing-grooves, similar to those used in somedescriptions of pump-plungers and other like work. Into this sleeve orbushing a hollow plunger, j, Fig. 2, is fitted, having at a suitablepoint a series of holes, Z Z, Fig. 2, which act as valves, as will behereafter described. Oii the upper end of said plunger there are twolugs, 7c k, Figs. 2 and 3, which serve as means of attachment for thebail-rods m m. The pump consists further of a valveboX, n, Fig. 2,having in the bottom a valve opening' inward, (in this case a ball ofvulcanized rubber,) marked o, on Figs. 2 and 3. On opposite sides ofthis valve-box there are two grooves, p p, Fig. 3, to permit the lugs kla of the plunger j to pass freely when the pump is in operation. Theupper end of this valve-box is provided with a flange, q, of suitabledimensions for securing it to the pumpbarrel- On the upper side of thisflange ,there are two bosses, r r, having holes through them a littlelarger than the diameter of the bail-rods m m, and recessed in asuitable manner for the reception of Babbitts or any other anti-frictionmetal. There are also two bail-rods, m m, fastened into the lugs L Zr,Fig. 3, which rods pass through the bosses i' i" on the iiange q, andare connected at the top by a yoke or bar, s, Fig. 2, to which isfastened the lower end of the pump-rod t, by means of which motion isimparted to the hollow plunger j. The whole apparat-us is surinounted bya chamber, a, Figs. l and 2, provided with a boss on its upper sidetapped to receive the discharge-pipe w. The flange on the bottom is madeto conform to the flanges on the pump-barrel and valve-box, and thewhole iirinly clamped or bolted together, as shown by Fi g. 2. Thisentire apparatus is screwed to the lower end of a piece of pipe of alength sufficient to reach the bottom of the well, or to any such depthas may be desirable, the upper part projecting through the curbing, andhaving secured to it any of the usual mechanical con trivances iii usefor giving to pump rods or plungers a vertical motion, and having alsoan outlet or discharge-nozzle.

At present I make no claim to any specific manner neither in the methodof operating the 'pump-rod which passes through the pipe, nor to themanner of discharging the water, inasmuch as these points will notconflict with the objects of my invention, and will have to be made tosuit special purposes and localities.

The operation of the pump is as follows: Vhen the plunger j is down thewater or other substance rushes through the openings Z Z of the plungerand fills it. The plunger now being raised by means of the rod t, theholes Z Z are closed by reason of their sliding into the sleeve lt, andthe water having no other outlet is forced to pass into the valve-box a,where the valve o retains it. Each successive stroke of the plungerrepeats the operation, and eventually discharges the water at the headofthe pipe. The leakage through the bosses i" i, although but slight,will prevent the water from standing in the upright pipe when the pumpis at rest, thus obviating any injury or inconvenience from freezing.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. The pump-barrel and strainer g, cast in one piece, and provided withthe flanges and the grooved bushiii g li, as herein set forth and shown,for the purpose specified.

2. The hollow plunger j, with holes Z Z and T CFFICE.
